Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die with a waste removal function. Background Technology
[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies. They use dies mounted on a press to apply pressure to the material, causing it to deform, thereby obtaining the desired parts. Stamping dies are generally mounted on a stamping machine.
[0003] Some existing equipment on the market generally has a waste discharge hole on the mold corresponding to the stamping head, and a waste discharge pipe is installed on the worktable. The waste discharge hole and the waste discharge pipe are connected. A waste collection tank is installed at the outlet of the waste discharge pipe. The waste material after stamping and cutting falls into the waste collection tank after passing through the waste discharge pipe, which facilitates waste discharge and waste collection at the same time.
[0004] However, in actual use, the arc-shaped surface inside the hole formed by the stamping process will develop burrs due to the pulling action of the stamping process. This may cause injury to workers if they accidentally touch it. In view of this, we propose a stamping die with a waste removal function. Utility Model Content
[0005] The purpose of this invention is to provide a stamping die with a waste removal function to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die with a waste discharge function, comprising a housing, an mounting plate fixedly connected to one side of the inner wall of the housing, an engine fixedly connected to the top of the housing, a lower die fixedly connected to the upper surface of the mounting plate, a collection box fixedly connected to the bottom of the mounting plate, a fixing column fixedly connected to the upper surface of the mounting plate, a hydraulic telescopic rod fixedly connected to the output end of the engine, a pressing head fixedly connected to one end of the hydraulic telescopic rod, a limit component fixedly connected to the arc-shaped surface of the hydraulic telescopic rod, a spring sleeved on the arc-shaped surface of the fixing column, an upper die sleeved on the arc-shaped surface of the fixing column, and a scraping structure provided by the pressing head, the scraping structure including a groove, the groove being provided on the arc-shaped surface of the pressing head, so that when the pressing head rotates, the groove can scrape off the burrs on the inner wall of the through hole formed by the stamping part.
[0007] Preferably, the upper surface of the upper mold has a through hole that corresponds to the through hole on the upper surface of the lower mold, and the through holes of the upper and lower molds are adapted to the size of the pressing head. The bottom of the upper mold is in contact with one end of the spring, which allows the upper mold to be lifted by the elastic force of the spring.
[0008] Preferably, the through hole on the upper surface of the lower mold communicates with the collection box, and the position of the pressing head corresponds to the positions of the upper and lower molds, which allows the pressing head to perform stamping better.
[0009] Preferably, the grooves are evenly distributed in a circumferential array on the arc-shaped surface of the pressing head, and the size of the limiting member is adapted to the size of the upper mold, which allows the limiting member to better apply pressure to the upper mold.
[0010] Preferably, the bottom of the limiting member is provided with a ball bearing, and the ball bearing is positioned at the bottom of the limiting member away from the hydraulic telescopic rod, which makes it more convenient for the limiting member to rotate.
[0011] Preferably, there are multiple balls, and the multiple balls are evenly distributed in a circumferential array at the bottom of the limiting member, which can reduce the friction between the limiting member and the upper mold.
[0012] Compared with the prior art, this utility model provides a stamping die with waste removal function, which has the following beneficial effects:
[0013] 1. This stamping die with waste removal function, in order to prevent the burrs generated in the stamping part after the equipment is stamped from being unable to be scraped off, the hydraulic telescopic rod extends to make the pressing head contact the stamped part. The pressing head passes through the through hole set in the upper die, so that the limiting part contacts the upper surface of the upper die. This makes the upper die press down. At the same time, the pressing head passes through the stamped part and passes through the through hole set in the upper surface of the lower die. This allows the waste material to fall from the through hole set in the upper surface of the lower die to the collection box set at the bottom of the mounting plate while the stamped part forms a through hole. At the same time, the engine rotates and the pressing head also rotates. This allows the groove set in the pressing head to effectively scrape off the burrs inside the through hole formed in the stamped part. The burrs can also enter the collection box through the through hole set in the upper surface of the lower die.
[0014] 2. In order to avoid the burr removal device being inconvenient to move, the bottom of the limiting part of the stamping die with waste removal function is equipped with ball bearings. This can reduce the friction between the limiting part and the upper die when the limiting part rotates in contact with the upper surface of the upper die, making it easier for the pressing head to rotate.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a stamping die with a waste discharge function, including a shell 1, an mounting plate 2 fixedly connected to one side of the inner wall of the shell 1, an engine 7 fixedly connected to the top of the shell 1, a lower die 3 fixedly connected to the upper surface of the mounting plate 2, a through hole on the upper surface of the lower die 3 communicating with a collection box 13, a collection box 13 fixedly connected to the bottom of the mounting plate 2, a fixing column 5 fixedly connected to the upper surface of the mounting plate 2, a hydraulic telescopic rod 8 fixedly connected to the output end of the engine 7, a pressing head 11 fixedly connected to one end of the hydraulic telescopic rod 8, the position of the pressing head 11 corresponding to the positions of the upper die 4 and the lower die 3, which allows the pressing head 11 to perform stamping better, a limiting member 9 fixedly connected to the arc-shaped surface of the hydraulic telescopic rod 8, the size of the limiting member 9 being adapted to the size of the upper die 4, which allows the limiting member 9 to apply pressure to the upper die 4 better, a ball bearing 10 provided at the bottom of the limiting member 9, and the position of the ball bearing 10 being set at the limiting member 9. At the bottom, away from the hydraulic telescopic rod 8, there are multiple balls 10, which are evenly distributed in a circumferential array at the bottom of the limiting member 9. This reduces the friction between the limiting member 9 and the upper mold 4, making it easier for the limiting member 9 to rotate. A spring 6 is sleeved on the arc-shaped surface of the fixing post 5, and the upper mold 4 is sleeved on the arc-shaped surface of the fixing post 5. The upper surface of the upper mold 4 has a through hole that corresponds to the through hole on the upper surface of the lower mold 3. The through holes of the upper mold 4 and the lower mold 3 are adapted to the size of the pressing head 11. The bottom of the upper mold 4 is in contact with one end of the spring 6, which allows the upper mold 4 to be lifted by the elastic force of the spring 6. The pressing head 11 is provided with a scraping structure, which includes a groove 12. The groove 12 is evenly distributed in a circumferential array on the arc-shaped surface of the pressing head 11. When the pressing head 11 rotates, the groove 12 can scrape the burrs on the inner wall of the through hole formed by the stamping part.
[0020] In this invention, during use, the hydraulic telescopic rod 8 extends to bring the pressing head 11 into contact with the stamped part. The pressing head 11 passes through the through hole provided in the upper mold 4, causing the limiting member 9 to contact the upper surface of the upper mold 4. This causes the upper mold 4 to press down, while the pressing head 11 passes through the stamped part through the through hole provided in the upper surface of the lower mold 3. This allows the stamped part to form a through hole, and the waste material falls from the through hole provided in the upper surface of the lower mold 3 into the collection box 13 provided at the bottom of the mounting plate 2 for collection. At the same time, the engine 7 rotates, causing the pressing head 11 to rotate as well. This allows the groove 12 provided on the surface of the pressing head 11 to effectively scrape off the burrs inside the through hole formed by the stamped part, and the burrs can also enter the collection box 13 through the through hole provided in the upper surface of the lower mold 3. Meanwhile, the bottom of the limiting member 9 is provided with a ball bearing 10, which reduces the friction between the limiting member 9 and the upper mold 4 when the limiting member 9 rotates in contact with the upper surface of the upper mold 4, making it easier for the pressing head 11 to rotate.
[0021] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
